將 output 文本存儲在 tkinter 文本框中

Question

我正在尋找 output 文本文件和 tkinter 文本框的文本列表。 目前我正在努力打印到保存在同一文件夾中的文本文件。 我希望將相同的列表打印在屏幕上的 outputToScreen 文本框中

根據我的研究，我認為我應該使用 .insert(index, text) 但我無法使這種方法起作用。 我也看到了一些使用 a.set function 的舊代碼，但是當我嘗試這個時，我遇到了一個錯誤，說文本框沒有那個方法

文本小部件索引是line.character形式的字符串，行從 0 開始，字符從 1 開始。因此，要在開頭插入，您需要使用索引“1.0”，而不是 0。如果您想在末尾插入您可以使用特殊索引"end" 。 如果小部件為空，則"1.0"和"end"會產生相同的結果。

outputToScreen.insert("1.0", outputToFile)
